SPECIFICATION forming part or' Letters Patent No. 767,047, CllSC-l August 9, 1904:.

Application led February 12, 1903. Serial No.143,049. (No model.)

Be it known that I, GEORGE B. Essex, a citi- Zen of the United States of America, residing at Detroit, in the county of Vayne and State oiI Michigan, have invented certain new and useful Improvements in Lubricators, or' which the following' is a specification, reference being had therein to the accompanying' drawings.

This invention relates to improvements in lubricators, and especially to that class of lubricators known as multiple Oilers; and its object is to provide a lubricator of the class which is especially adapted for use on automobiles or the explosive-engine type, the construction being such as to require no especia-l attention, as the flow of oil is automatically controlled so that when the eng'ine is stopped the 'low of oil will cease.

1t is also an object ot' this invention to so construct the device that the sight-fecd an d the supply-tank thereof are entirely separate from each other, so that each may be located in the most desirable place; and a further object oi the invention is to provide a simple and cheap multiple sight-feed which is easily assembled and may be suppoi'ted in any convenient place, all as hereinafter more fully described, reifen ence being had to the accompanying' drawings, in which-A Figure l is a side elevation or' the multiple sight-feed of the oiler with portions broken away to show the construction; Fig. 2, a section of the same on the line Q 2 or' Fig. 1, and Fig. 3 is a view illustrating' the manner oi' connecting the sight-feed and its supply-tank with the engine.

A is a suitable oil-supply tank, which may be located Wherever desired, preferably where it uwill be kept warm by the heat from the engine, and is connected by a pipe B with the exhaust or the engine at any suitable point so that a portion of the discharge will pass through said pipe into the top or' the tank and create a pressure therein. An oil-supply pipe C extends through the top of the tank and downward therein to near its bottom, so that the oil in the tank will be forced by the pressure in the tank upward through said pipe C to the multiple sight-feed D, to which said pipe is connected at its opposite end. A valve E is provided in the top o'l the tank, so that should the pressure in said tank become too great it will open, and as said pipe B is connected tothe exhaust valve, passage, or mur'- fler of the engine at a point where the exhaustpressure is nearly uniform the pressure in said. tank will vary but little while the engine is running; but when the engine is shut down the pressure in the tank will immediately run down, as there is no check-valve inthe pipe B, and no more oil will be -fed.

The multiple sight-'feed l) consists of a suitable casting or head F, which is cored out near its upper end to form a longitudinal duct or chamber ll", with which the pipe C communicates through the opening' F, and said cast ing is cored out near its lower end to forni a chamber F, which chamber is formed with lateral sight-openings F" through the sides or' the casting. A series of holes are bored in the upper end of the casting, through the wall thereof, into the duct 1W, and into these holes are screwed a series of needle-valve fittings G, consisting oil.2 nipples (if, through each of which passes a screw-threaded stem (l2, having a needle-point at its lower end to engage a seat G, formed in the bottom of the duct, and a milled head on its outer end, said nipples also being provided with packing-mits ir".

Projecting downward into the chamber F3 from the wall separating' the duct F' from said chamber are the integral nipples H, and a small hole H.' is bored from the seat Gr" through said wall in the axis of each of said nipples to conduct the oil from the duct F. A series or' holes are also bored through the wall at the lower end ot' the casting into the chamber F to receive a series of glass sight-tubes l, which engage recesses surrounding the nipples 1I. :in the upper wall of the chamber and are held in place by suitable littings J', screwed into said holes, which littings J consist of the hollow nipples J', provided with the packingnuts J2 to secure the ends oif the tubes .K thereto, said tubes being provided to conduct the oil to the various parts to be lubricated.

The needle-valves being set in a row and close together in the casting and said casting being just thick enough to receive said valves, a very compact device is secured, which may be read- IOO ily attached to the dashboard of the Vehiclebody, where the feed may be watched and regulated, the sight-openings lj exposing the glass tubes to View.

Having thus fully described my invention, what ,I claim is In u multiple oilei, the combination with an oil-supply tank; of a multiple sight-feed consisting of L casting formed with a longitudinal oil-duct near its upper end, a chamber near its lower end, openings on the side walls of said chamber, sinall holes through the wall between the duet and chamber, nipples extending downward into the chamber, recesses in the wall around said nipples, and holes in the lower wall of the chamber in line with the nipples; a series of needle-Valve fittings secured to the upper end of the casting and having valve-stems extending across the duct and engaging' seats in the small holes, sight-tubes engaging the recesses around the nipple at one end and the holes in the wall below the cheniber at their opposite ends, ttings within the said holes and tubes secured to said ttings.

In testimony whereof I aiX my signature'in presence of two witnesses.
